A close look:

I would like to question the design intent of the hose.

if we took a look at where it starts and ends, [both end points are on the driver side], there seems-to-be/is no reason for the hose to loop across the bottom of the vehicle to the passenger side, only to reroute back to the drive side...

disappointed in the wastefulness of the design when this hose could have been design to be less than 1 foot long, also reducing its potential failure points, cost to replacement, and manufacture.
